RUSSELL V. BROWN, OF PROVIDENCE, RHODE ISLAND.

IMPROVEMENT IN NEEDLE SETTER AND THREADER.

Specification forming part of Letters Patent No. 104,260, dated June 14,1870.

To all whom it may concern:

Be it known that I, RUSSELL W. BRowN, of the city and county ofProvidence, in the State of Rhode Island, have invented a new andImproved Needle Setter and Threader; and I do hereby declare that thefollowing specification, taken in connection with the drawing making apart of the same, is a full, clear, and exact description thereof.

Figure l is a perspective view, showing the gage in the eye of theneedle. Fig. 2 is the same with the gage removed. Fig. 3 shows themanner of threading. Fig. 4 is a top view with spring opened to receivethe needle.

My invention consists in the device hereinafter described, and isdesigned to be used in connection with sewing-machines, and to operateas a gage in adjusting the needle to the machine, and also to facilitatethe threading of the same after a proper adjustment has been obtained.

It is well known by those familiar with the use of sewing -machines thatnot only the quality of the work but thepreservation of the needleitself depends upon its proper adjustment to the needle-bar. Its properadjustment, however, without the aid of a suitable device is attended"with much inconvenienceit not being of sufficient size to be easilyhandledand with much uncertainty, for the reason that the eye is unableto measure the distance with the necessary accuracy.

The needle, when attached to the machine, is held firmly in aperpendicular position, and much below a convenient height for threading. It is therefore, especially when a fine needle is used, a matter ofconsiderable diflioulty to thread it, and much time and patience areoften exhausted.

I overcome these difficulties by the use of a setter and threader, whichconsists of a flat piece of metal, A, Figs. 1, 2, 3, and 4, a spring, B,lever O, and arm D, which is pivoted to the piece A at one end, theother being provided with a sharp point at right angles thereto.

The operation of my invention is as follows: Push back the spring B, bypressing the thumb upon the lever G, and insert the needle be. tween thespring and the piece A, which are grooved to receive it, and let thepoint of the needle extend downward to a distance which will enable theeye to receive the point upon the arm D, as shown in Fig. l.

The point of the arm D may now be removed from the eye, as shown in Fig.2, and the upper end of the needle inserted in the needlebar until thescrew E rests against the end. of the same, when the needle is securedto the bar, in the usual way, by means of a thumbscrew.

The adjustment of the needle is now complete, the threading remaining tobe done. For this purpose I move back the arm D, as shown in Fig. 3,place the point of the same behind the needle, instead of inserting itin the eye, as before described. The end of the thread is then placed ina horizontal groove upon the arm D, which conveys it to the eye of theneedle.

My device may be adjusted to different machines by raising or loweringthe screw E.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the piece A, spring B, lever C, pivoted arm D, andscrew E, the whole constructed and arranged in the manner described.
